Biodegradation of polyester polyurethane by endophytic fungi.
Bioremediation is an important approach to waste reduction that relies on biological processes to break down a variety of pollutants. This is made possible by the vast metabolic diversity of the microbial world. To explore this diversity for the breakdown of plastic, we screened several dozen endophytic fungi for their ability to degrade the synthetic polymer polyester polyurethane (PUR). Sever...
متن کاملComputational Design of Molecularly Imprinted Polymers
Artificial receptors have been in use for several decades as sensor elements, in affinity separation, and as models for investigation of molecular recognition . Although there have been numerous publications on the use of molecular modeling in characterization of their affinity and selectivity, very few attempts have been made on the application of molecular modeling in computational design of ...
متن کاملMicrostructure Changes in Polyester Polyurethane upon Thermal and Humid Aging
The microstructure of compression molded Estane 5703 films exposed to 11%, 45%, and 80% relative humidity and 70 ̋C for 1 and 2 months has been studied by small-angle neutron scattering (SANS), Fourier transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC), and differential scanning calorimetry (DSC). Scattering data indicated increase of the interdomain distance and domain...
متن کاملFungal communities associated with degradation of polyester polyurethane in soil.
Soil fungal communities involved in the biodegradation of polyester polyurethane (PU) were investigated. PU coupons were buried in two sandy loam soils with different levels of organic carbon: one was acidic (pH 5.5), and the other was more neutral (pH 6.7). After 5 months of burial, the fungal communities on the surface of the PU were compared with the native soil communities using culture-bas...
متن کاملNEXAFS spectromicroscopy of polymers: overview and quantitative analysis of polyurethane polymers
The successful application of X-ray spectromicroscopy to chemical analysis of polymers is reviewed and a detailed application to quantitative analysis of polyurethanes is presented. Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy is the basis of chemical sensitive X-ray imaging, as well as qualitative and quantitative micro-spectroscopy. These capabilities are demonstrated by a ...
